Abstract (en)

[origin: WO2015027004A1] A kinetic heat sink has a stationary portion with a first heat-conducting surface and a second heat-conducting surface to conduct heat therebetween. To cool heat generating devices devices, the stationary portion is mountable to a heat-generating component and has a first plurality of fins extending therefrom. The kinetic heat sink also has a rotating structure rotatably coupled with the stationary portion. The rotating structure is configured to transfer heat received from the second heat-conducting surface to a thermal reservoir in thermal communication with the rotating structure. The rotating structure has a movable heat-extraction surface with a second plurality of fins extending toward the first plurality of fins. At least a portion of the first plurality of fins preferably are interdigitated with at least a portion of the second plurality of fins.
